Jeff Hoogland has announced an early development snapshot of Bodhi Linux 5.0.0. The new alpha release is based on Ubuntu 18.04 LTS and runs the Moksha desktop environment, which is a fork of Enlightenment. "Some highlights about these 5.0.0 ISO images: Ubuntu 18.04 base; Moksha 0.3.0 testing release; 32-bit and non-PAE support with 4.9 kernel in Legacy ISO image. Please note the focus of these ISO images was simply getting Moksha up and running on the Ubuntu 18.04. I have yet to clean out the ISO images of excess clutter or ensure that everything we expect to deliver a full Bodhi experience is present. We hope these discs will help serve as a testing ground for some of the changes we have been back porting for Moksha before we tag a 0.3.0 release of the desktop."

The Kwort distribution has published a new release, Kwort 4.3.3, which incldues two compilers and several key package updates. "Well, this was supposed to happen, our system has highly increased its size. Not that too many dependencies were added, but LLVM, which [is] huge, is now part of the standard image. Hopefully we'll have again one compiler in the future, but for now we need two. Having said that the system keeps being simple and fast and with everything on the right spot. Most significant technical aspects are: Linux kernel 4.14.40. New toolchain with glibc 2.27, gcc 7.3.0 and binutils 2.29.1. New kpkg has some new features and new documented (in the man page) variables to make it less error prone and more automated.

Fredrik Rinnestam has announced the release of CRUX 3.4, a new stable version of the distribution's lightweight, x86-64 optimised Linux distribution designed for experienced Linux users: "We are happy to finally announce the release of CRUX 3.4. The toolchain has been updated to include glibc 2.27, GCC 7.3.0 and Binutils 2.29.1. CRUX 3.4 ships with a 4.14.40 installation kernel and X.Org 7.7 with X.Org Server 1.20.0. The ISO image is processed with isohybrid and is suitable for burning on a CD and putting on a USB drive. UEFI support is available during installation with dosfstools, efibootmgr and grub2-efi added to the ISO image. Important libraries have been updated to new major versions which are not ABI compatible with the old versions. We strongly advise against manually updating to CRUX 3.4 via ports, since these changes will temporarily break the system. Please note that there may still be packages that need updating which are not included on the ISO imgage. These packages will need to be updated/rebuilt manually."
